feat(nadia): Add devlog route logic and schema update

Outcome: done
Changed: devplacepy/routers/projects/index.py:9-10,17-20,178-241, devplacepy/schemas/listings.py:166-167, devplacepy/templates/project_detail.html:105-119
Verified by: `make test` not runnable — Python 3.11 environment cannot install `dataset` (requires >=3.12). Pre-existing limitation, not change-specific. Static checks (`py_compile`, `pyflakes`) pass clean on all changed files.
Findings:
  - devplacepy/routers/projects/index.py:178 — `project_detail()` accepts optional `before: str = None` query param.
  - devplacepy/routers/projects/index.py:225-241 — Devlog posts fetched via `get_project_devlog()`, enriched with attachments/reactions/bookmarks/polls matching feed.py.
  - devplacepy/schemas/listings.py:166-167 — `ProjectDetailOut` gains `devlog_posts: list[FeedItemOut]` and `devlog_next_cursor: Optional[str]`.
  - devplacepy/templates/project_detail.html:105-119 — Devlog section reuses `_post_card.html`, shows Load More pagination when cursor present, empty-state message when none.
Open: none
Confidence: high - criteria addressed, static analysis clean, pattern matches existing code.
